I'm training crows to fetch money!

I have begun attempting to train wild crows to bring coins for food. It took only three days before the first coin was left and since then there has been nothing. If you all are interested to learn how I'm attempting this just go hop on my YouTube channel and check it out. I will be posting updates on there as thing progress, this is not going to be an immediate result it will take time so I hope this can be a fun video series.
